Rising damp: causes, signs and solutions
Marks at the base of a wall, salt deposits or peeling paint? Understanding where damp comes from helps you choose the right approach. Recognise the signs of rising damp and compare our ATE and ATG devices.
How rising damp develops
Water from the ground can rise through pores in materials such as brick, stone and mortar. It affects masonry in contact with damp ground, particularly where a damp-proof barrier is missing or damaged. Materials and building conditions influence how it develops.
Signs to look for on your walls
Marks usually appear near the base of the masonry. Salt deposits, crumbling plaster, blistering paint and loose finishes can accompany them. Consider these signs together: a single stain cannot confirm the cause of damp.
Distinguishing rising damp from other causes
A plumbing leak, rain penetration through a wall and condensation on a cold surface require different responses. Our devices are intended for rising damp and do not repair leaks, waterproofing defects or condensation problems. Identifying the cause helps you choose appropriately.
Choosing an ATE or ATG device
ATE and ATG devices are designed to support progressive drying of affected walls, without chemical injections. ATE devices connect to the mains; ATG devices work without electricity. Compare the technology, coverage diameter and installation requirements before choosing.
Progressive drying depends on the building
Materials, wall thickness, finishes, ventilation and installation conditions affect drying. An 18–24 month period is indicative and does not guarantee complete drying. Our team can help you compare models and installation manuals.
