Damp Proofing, Electro-osmosis & Silane Diffusion

We specialise in the followings areas;

Damp Proofing

What is rising damp? It is the process of capillary action, where ground water rises into brickwork or masonry that does not have an effective damp proof course (dpc). In older buildings a dpc may never have been incorporated into the wall construction, or the dpc may have been bridged by raised ground levels or alterations to the building or the dpc may have been degraded and failed. Salts left by rising damp can absorb moisture from the atmosphere leading to wall dampness in conditions of high relative humidity. This will result in spoilt and degraded plaster surfaces and decoration. It is vital therefore that appropriate replastering work is undertaken where required, following the successful installation of a new damp proof course.

Electro-osmosis

The electrical potential, which originates when water in a masonry wall causes water molecules to wander away from the plus to the minus pole. Electrical osmosis was discovered by the physicist Reuss some 200 years ago. The principle to dry out damp walls using this natural principle was developed by Lectros International Ltd. In the mid 1970s using state of the art materials and modern equipment. The Lectros Osmotic Damp Proofing System has been installed over 80,000 properties over the last 30 years including Chatsworth Estate, The Presidential Residence Dublin, Manchester University, Bishops Palace & Ely Cathedral. Eradakil Ltd has enjoyed Lectros Approved Contractor status for over 25 years. In an ever conscious world striving for greener, safer products, the Lectros system leads the field. The system is chemical free and therefore safe for the environment, and with no health risks.

Silane Diffusion

Utilising a concentrated thixotropic silane/silicone cream to form a barrier against rising damp. As the cream slowly diffuses, it releases a silane vapour, which reacts with the silica in the masonry to form a water repellent resin. The system is delivered by injection via bore holes that are drilled into a horizontal mortar bed at the base of the wall.
