Problem
Concrete is naturally porous and should not be considered to be a water-tight structure. Water will slowly seep through tiny pores in the concrete and this is exacerbated when the water is under pressure.
Before a structure can be used, it must be made waterproof and tanking is an ideal way to do this.
Tanking is a procedure for providing a waterproof or vapour-proof internal or external lining to a structure.
Before tanking can be carried out, ancillary actions such as sealing joints must be undertaken to prevent future leaks.
Joints between concrete blocks or mortar in brickwork/blockwork are weak points in a structure and therefore more likely to leak.
Internal corners are subject to large stresses and this often leads to cracking allowing water ingress.
Pipes or light fittings that are cut into/through the concrete are also very likely to leak unless correctly fitted.
Solution
Use weber.cem dry structural waterproofing products
Even properly designed water retaining structures may not be totally watertight and curative measures need to be taken.
Remedial waterproofing can be a risky operation. Success or failure is visible immediately but risk can be minimised by understanding the causes of the problem and providing effective solutions through the application of user-friendly high performance products by specialist applicators.
