After the installation of a damp proof course (DPC), the affected mortar will often need to be replaced through the process of repointing. Tech-Dry looks for the most practical and cost-effective approach when providing a quote for repointing.
The repointing process commences after a DPC has been installed and given sufficient drying time. The loose mortar is removed to a pre-determined height (typically along an even plane at the level to where the damp has risen) and at a minimum depth of approximately 10 – 15 mm. The new mortar contains a mixture of sand and cement, with a water proof additive to help protect against residual salt left in the masonry wall.
