Rising Damp & Mould Treatment
Rising damp is a phenomenon where part of a building is below ground and the ground moisture & water wicks up and through the substrate from the soil. The pressure of the water is known as Hydrostatic pressure
Rising damp can have implications such as:
- Structural Damage through constant saturation of the substrate, whether it be concrete or timber. Concrete cancer, spalling and rotten concrete reinforcement can result from constant saturation and can be very costly to repair. Timber can rot or decay and develop mold, affecting the structural integrity of the dwelling.
- Health implications through the growth of mold. The constant wet conditions are the perfect environment for mold to thrive. Certain molds are not visible to the eye and can wreak havoc on your health.
- Damage to your personal belongings and potential decrease in your homes value. Water damage, typically below ground is usually damage to your foundations or weight bearing walls. It is very important that these stay rigid and free from water damage. Homes with water damage can be very costly to repair therefore the value of your home or dwelling can be considerably reduced when water damage is present.
Able Waterproofing offers many solutions for rising damp and groundwater issues, froom both the positive and negative sides. Common products used are
- Hydrostatic Epoxies.
- Cementitious Membranes.
- Cement based water plug mortars.
- Polyurethane injection.
Positive waterproofing is usually done in the construction phase and is done before the land is backfilled against the substrate. This is the most effective form of waterproofing and the best way to prevent rising damp as it keeps the whole substrate, inside and out of the wall or foundation, free from water.
Negative waterproofing is from the opposite side and stops water penetrating through the face of the substrate. This is effective in stopping water from leaving the substrate although the substrate is still holding water. This is a common solution when waterproofing was not done initially or the waterproofing has failed.
