Water Proofing of Ground Floor Areas

Water proofing and stopping moisture from entering

Water and moisture can cause a lot of damage and considerably reduce the value of your home or commercial building.

When moisture enters an area, it sets up the perfect environment for the formation of mould, and once mould has been established, it will continually produce spores and release them into the surrounding air. These spores then spread throughout the rest of the home or building causing a damp smell and can increase the risk of health disorders and living quality.

Water or moisture entering basements or garages can usually be traced to groundwater or moisture entering through the floor slab or the basement walls. Or it can be as simple as a garage that doesn’t have a proper drainage system preventing groundwater from entering through the garage door in wet weather.

Signs of this are:

• rottting flooring
• damp carpet floor
• rottting gib board
• the damp or musty smell in a room
• paint falling off or discolouration to your walls
• Your possessions may also be affected and will feel damp and cold or have mould or mildew

Waterproofing & drainage of house basement

While this mostly affects older buildings, new buildings can also be affected.

You can buy do-it-yourself paint on products but these don’t last long. We have even seen some drainage companies using these products. It is a short-term fix for a bigger problem and it doesn’t deal with the cause of the water ingress.

Some other companies will tell you just to use an interior solution that has a long lifespan. In our experience, if you don’t also allow the water outside the structure to be removed the problem will recur and there is the potential for water to cause structural damage which will result in more costly repairs later on.

Waterproofing your biggest asset is an area we specialise in. Tackling the problem on the exterior first and stopping moisture water entering basements, bathrooms and living areas all over the North Shore, Hibiscus Coast and throughout the Greater Auckland area.

We use excavation and drainage in conjunction with a specialised waterproofing membrane applied to your exterior wall. We use this when the outside ground level is higher than the inside ground level of a house. This is generally found in garage and basement areas. In this situation water moisture from the outside makes its way through the ground rubbing up against the house into the blockwork, bricks or cladding and into the inside framework rotting out the gib board and framework.

Waterproofing

To fix this we excavate down the side of the house to below the foundations. To discharge the water away from your problem area and into the stormwater system. We prepare the affected area until it is clean and ready for waterproofing.

We waterproof the whole wall from foundations to above ground level with a durable membrane and apply additional protection to the waterproofing membrane. The specialised membrane we use will stop any excess water or moisture from intruding into exterior walls and showing up on the inside of your house or building. This process prolongs the lifespan of the waterproofing.

This system effectively stops water entering into the blockwork or other materials used in the affected area. Groundwater will flow through the scoria material into a novacoil pipe and away from the house. At the same time the waterproofing process protects the outside wall preventing moisture entering the house and causing damage.

All the products we use are New Zealand approved for our environment. We are approved applicators and provide a written 15 year warranty at completion of our work.
