Professional Damp Proof Course

If your house suffers from rising damp and the cause is not a simple damp bridge, then the damp proof course (DPC) has probably failed. The quickest and least expensive method of installing a new damp course is to inject special silicone liquid into the brickwork all round the house, along the line of the existing damp proof course. It is possible to hire the equipment and inject the liquid yourself, but there are several reasons why this is best left to a specialist contractor.

Firstly, the job can be technically quite difficult to carry out properly, especially if the house has cavity walls or the damp has also affected internal load-bearing walls. Since some of the brickwork you are trying to treat is concealed, you therefore have no way of knowing whether you have completely saturated it or formed a continuous damp barrier. A professional installer can ensure this.

Secondly, a professional firm will give you a guarantee for its work; although this is only worth having when something goes wrong if the firm is still in business. Therefore, employ a firm which is a member of the Wood Preserving & Damp proofing Association.

If you plan to have your cavity walls insulated, you must first of all apply to your local authority for Building Regulations approval for the work. The building inspector will advise you on the suitability of the various materials used for your particular location (there are restrictions on the use of urea-formaldehyde foam in exposed locations, for example). He will also want to ensure that the firm which will be carrying out the work is approved by the Building Institute or is installing a product that is certificated by the Building Board of Agreement (BBA).

All the materials used are injected or blown into the cavity through holes drilled in the outside leaf of the wall. Make sure that the firm checks whether your wall cavities are open or closed at eaves level; if they are open, insulation - especially foam - can find its way into the loft.

Problems can also arise at other points where the cavity is bridged and not sealed. In particular, care must be taken to keep air-bricks and ventilators open.

If you live in a semi-detached house, try to persuade your neighbor to have his walls insulated at the same time. You will get a price reduction from the installer for treating two houses at the same time.

DIY damp proof cream – Proper Solution of Damp

If you are on a budget and have a damp space, why not save up on damp treatment cost and do it yourself? There are many products available with robust information and tips on using them that allows for us at home to treat the damps on our own. Yet, before you damp proof your home, make sure you know what type of problem you are facing, as different products are meant for different problems. Using the wrong products may worsen a problem.

First of all, you will need to establish what type of damp roofing job you are dealing with. If your property is above ground, this is a pure damp roofing job. However, if you are looking at a damp basement, this is not actually a damp roofing job as there is purposely a drainage system within the walls of the basement, and injecting a damp proof cream may hinder proper drainage. There should also be damp proof courses along your house. If it is defective, that would be the best place to do your DIY damp proof cream

One of the ways is to use DIY damp proof cream on the damp structure of bricks. You just mix the cream with the mortar and the dampness will not exceed that height. While this is an easy method, this is not suitable for structures built with random stones. For this situation, you can use the dimpled meshed damp proof membranes instead, which are widely available in the market nowadays. What it does is that it creates 'dimples' or air gaps where it will allow the dampness on the wall to dry off. Then, apply plaster onto the damp proof membrane, which will take the place as the wall's new surface. Although you want to save on damp treatment costs, this second method should actually be carried out by specialists so that you get your money's worth of product used. Furthermore, damp membranes are a permanent solution, so do take it as an investment. Likewise, basement waterproofing should be done by specialists so that you do not mistakenly hinder certain damp courses.

Difference Between Damp proofing course And Course and Waterproofing Is Course

There are many benefits associated with damp proofing course. of course your basement but this is something that must be done during the construction of your home. When building a new home many companies recommend that a damp proofing course treatment is used on the outside of the walls while it's being constructed. This will be done with liquid asphalt that will be painted over the outside of the walls and its purpose is to help seal the moisture out once the home is finished.

It is very important to realize that damp proofing course  is not the same thing as waterproofing your home. Many people get these two mixed up and that could cause a lot of problems in the future. Damp proofing course  will help to keep the dampness from entering your basement but it will not stop water from leaking in through cracks nor will it completely prevent water from being absorbed by the materials used to build the home. That's why it's so important that you go one step further and waterproof your basement as well. This way, you won't have to worry about moisture entering your basement and doing damage to your home and your health.

There are many benefits associated with both damp and waterproofing your home. For instance, once the project is finished, you have an extra space in your home that you can be used for anything from a recreational area to an extra bedroom. Damp proofing course  will help prevent your basement walls and floor from absorbing moisture from the ground and waterproofing can prevent water from leaking into the home through small cracks and porous materials. There are several methods used in waterproofing and the one that you need to use will depend on what materials were used in the construction of your home. This is due to the fact that certain products work better with some materials than they do with others. For example, you would need to use a different type of waterproofing product on masonry than you would if your home had a brick frame.

If you need to choose between damp proofing course  and waterproofing your home, it's recommended that you go over the construction plans for your home to see if which one would be beneficial for you. If your home is being built in an area where the soil is sandy and the drainage is very good, then you could greatly benefit from a damp proof home. However, most homeowners will agree that waterproofing is more beneficial for most areas even though it does cost quite a bit more.

Of course, in homes already built, you don't have a choice and you should seriously consider waterproofing your home because it can save you a lot of money in the long run. If your basement feels damp when you walk through it, boxes feel wet or the air smells musky, then you have a problem with moisture. Taking care of this problem will improve the air quality in your home, prevent damage to the structure and foundation of your home and make it possible for you to make good use of this extra space. Damp proofing course  might cost you a bit of money now, but you can rest assured that it is money well spent.

Damp Proof Course Permanent Solution of Damp Problem

Damp problems in buildings are problematic whether they be above the ground - damp walls - or below ground in a damp cellar or basement. Damp injection has been the most popular remedial solution in recent years but this is not an effective solution in cellars, has limited effectiveness above the ground and certainly will not stop condensation damp, rising damp or penetrating damp.

Injected chemical damp proof course damp treatments need to be precisely installed to be anywhere near effective, they are often messy requiring the wall plaster to be removed and are especially hit and miss in random stone and particularly thick walls.

Injected damp proof course are only designed to be effective against rising dampness and will not give protection against penetrating damp caused by adjacent high ground levels or wind driven rain. So injected chemical damp proof courses should be considered to be a prohibitive measure against rising dampness but should not be expected to be a cure for the detrimental effects caused like damp plaster, staining, salting, peeling decorative finishes etc.

However, there are products and methods that can be used for treating damp that will provide a once and for all permanent solution to your damp problem whether it be penetrating or rising damp.

The damp protection I am referring to is cavity membrane systems. These damp proofing systems comprise high density polypropylene and polyethylene membranes which are moulded into a stud or egg box type profile. The damp proof membranes are applied directly to the walls affected by the damp problem, and also are suitable for floor surfaces with a damp problem. They are secured into position with purpose made fixings ready to receive the new internal finishes.

For above ground damp problems they can be used in conjunction with or instead of an injected damp course. For below ground projects with damp problems like damp cellars or wet basements the cavity drain damp proof membrane systems are installed to the walls and floors and supplemented by drainage to remove any water collected.

Once applied to the wall surface the membrane provides a separation barrier between the damp walls and new internal finishes. The damp problem is dealt with because the impermeable nature of the damp proof membrane protects the wall finish and does not allow moisture, moisture vapour or the associated ground salts to migrate and cause damage. The stud pattern of the damp proof membrane provides an air gap for moisture to evaporate into without changing the status quote of the wall which means that the damp problem is not just pushed to adjacent areas.

Some damp proof membranes have a mesh welded to them and this provides a base for plastering direct or 'dab' fixing plasterboard. Other finishes include timber battens and plasterboard and timber or metal dry lining systems.

Not only are the systems promoted as permanent solutions by the manufacturer, they can also benefit from an installation guarantee when installed by a damp specialist. Contractors should offer insured installation guarantees for between ten and twenty years and some have the ability to take on full design liability.

Damp Proof Course – Complete Guide

Generally we have observed the paint falling off from the walls, the reason is always suspicious. We always tried to overcome this by painting the wall again and again however the result is the same. Now the question is how to get rid from this problem?

What is Damp Proofing?

Definitions:

Damp proofing in construction is a protective measure applied to the exterior of building foundation walls.

An application of a water-resisting treatment or material to the surface of a concrete or masonry wall to prevent passage or absorption of water-proofing a masonry surface to retard capillary action and water leaks.

One or more coating of a compound that is impervious to water.

A method used to prevent moisture entering the building.

Source of Damp Proofing

The major source of damp proofing is the rising damp. This allows water to rise up from the ground and into the walls of the building where it can cause water damage. The water along with the salts that are hydroscopic means they attract water. The salt still attracts moisture from the air in to the walls, keeping the walls damp. This damp stays in the walls of a home and mold and fungus will start to grow and can cause health issues. There can be structural damage in the damp walls.

How to get rid from Damp Proofing?

A  damp proof course ( DPC ) is a physical barrier inserted into the fabric of a building to stop water passing from one place to another. This can be on a horizontal plane, stopping water rising up from the ground by being sucked up by the dry masonry above, or vertically to stop water passing from the outside of a building, though the masonry, to the inside. DPC's have taken many forms through the ages and one of the earliest forms was to use a layer of slate in the construction. Slate is still used but the less expensive plastic version is now more widely used.

A horizontal damp proof course is inserted 6 inches above ground level, and used with a damp proof membrane which stops water the water from rising to any part of the ground floor from ground. It is usually a thick plastic strip inserted into the mortar between two courses of bricks or blocks. It can often be seen as a thin plastic line in the mortar near ground level.

In instances where the damp proof course has failed, where there is no damp proof course , or in other cases where the damp proof course has failed, a chemical DPC can be used in damp proofing. One method of doing this is to drill a hole at regular distances in the masonry course and insert the cream. The cream will then form a barrier that can prevent rising damp. We can use this technique however we have to consult with a professional to look at the property just because rising damp is not the only reason for dampness in a property, and repairing the DPC sometimes may not solve the problem.
