Essential Tips For Damp Proofing A Basement

There are several methods to achieve effective basement waterproofing. You can either block the passage of water into your home with cementitious or external waterproofing. Alternatively, you can control the ingress and flow of water to a pre-determined evacuation point by the use of cavity drainage systems.

External waterproofing has always been a difficult task. Due to the rise of water tables, an increasing number of basements and earth retaining foundation walls are being subjected to hydrostatic water pressure leading water to enter the building. The problem can be solved by using a combination of waterproofing products. It can be solved by using 3 simple treatments.

First of all, you will need to make the masonry pores narrower, making the surface water repellent. The product to use for this is Aida’s Kiesol silification spray, simply spray on the affected areas and leave to dry.

Next, you need to create a waterproof coating. To do this, add two coats of the plastic modified bitumen coating.

Now you can cover the surface with a cavity drainage membrane. This system will automatically elevate the hydrostatic water pressure from the building as it allows the water to drain freely through the filter fabric into the cavity.

Cementitious waterproofing, often known as waterproofing slurries, offer a thin layer of waterproof cement when applied to walls, floors, and ceilings of basements. These are designed to bond with the existing masonry substrate and will set to create a durable layer. This method will ensure that the basement walls remain dry and breathable.

Newton Membranes and Delta Membrane are designed to control the passage of water using cavity forming membranes, drainage channels and sump and pump water evacuation systems. They come in a variety of shapes and sizes to suit any damp proofing job. If you are damp proofing your own basement, follow this basic steps before you get started:

• Remove everything from your basement

• Clean your basement, removing any debris, dirt and dust

• Access the walls for any damage. You might need to fill in holes or dents before surfacing

• Be prepared, read the instructions before attempting to install any damp proofing solution

If you are concerned by the severity of your damp proofing problem, seek specialist advice. Technical staff will be able to advice you on the correct products and solutions to achieve effective basement waterproofing.
