As a result of the porous nature of walls, they are highly susceptible to rising damp, which can cause a great deal of damage structurally as well as aesthetically. It is for this reason that is also important to waterproof walls in any building. Although there are several methods, dampproofing is actually a minimal preventive measure used to keep water from passing through a wall. It is usually applied to the exterior foundation walls of a structure to protect it from moisture and any ensuing damage.

The problem of rising damp stems from several sources, including the failure – or in the case of older buildings – the complete lack of a dampproof course. The pores within most concrete and masonry surfaces allow the damp from the ground to rise up, usually accompanied by ground salts like chlorides and nitrates. It is these ground salts that absorb the moisture from the air that results in wall dampness, which has a high occurrence in particularly humid areas. The added moisture in exposed walls can not only cause structural damage, but can also affect the outside façade of a building, damaging any decorative features and even cause the corrosion of internal plaster.

If you are unable to install a complete waterproofing system, dampproofing may be the right option for you. Usually carried out using specialized liquid materials, the process is cost effective. At Richmond Primoid, we offer a choice of the best liquid systems available depending on your individual dampproofing needs to ensure that your building is left with the most effective waterproof walls.
