Rising damp is when water from the ground enters the structure by capillary action making its way up the walls and stops at about 3ft (approx. 1m). This is usually controlled by using a physical barrier or damp proof course (DPC) at a minimum of 150mm above ground level; this takes into consideration rain splashing onto the wall above DPC level and also elevated ground levels. If there is no DPC in place, if it has been damaged or has deteriorated then it is possible to install a remedial DPC to control the rising damp. It can only be cured by installing a chemical DPC.

Once the DPC has been installed the walls will need to dry out. The rate at which the wall will dry is 1 inch per month per thickness of wall, if well ventilated and unrestricted both sides of the wall. So for example a 9 inch thick wall will take 9 months to dry out. Because of this drying out time the damp/water vapour will affect any finishes i.e. plaster, paint. To prevent this from happening use Delta PT Lath or PT slimline membrane. When fixed to the wall it creates a cavity that allows the wall to dry out and breathe. It has a mesh welded to the face of it so you can plaster, render or dot and dab on top giving a dry internal surface that can be decorated immediately.

Basement Waterproofing

Sealing your basement and keeping it dry is achieved by managing the water and vapour that enters the structure, using drainage channels it is drained and directed into a sump chamber and pumped to a suitable outlet i.e. main drainage outlet at ground level. It is advisable to take out a service plan to maintain your pumps, we recommend to use Packaged Pump Systems. Click here to visit their website for full details.

The sump pumps come with a high level alarm with the option of having a messaging system that sends alerts to up to five phones. Battery back ups are recommended in case of power cuts to keep your pumps working at all times.

Water Management using drainage & sump pumps

A Koster tanking system can also be applied prior to the Delta system to help slow down the ingress of water and vapour reducing pumping cycles, as well as protecting against chemicals such as salts and lime which could potentially block the membrane system and cause damage to your pumps. This will in turn save you on electricity and pump repair costs.
