Clean the wall without overlooking the material
Retaining walls sit close to soil, garden beds and runoff, so they collect mould, dirt and staining faster than many other exterior surfaces. The right cleaning method depends on whether the wall is brick, block, stone or another suitable masonry product.
Waterworx uses pressure cleaning where suitable and can assess specialist treatment for mortar residue and stubborn masonry staining. Acid washing is specialist work and should only be used where the material and condition allow it.

Waterworx can assess excess mortar on suitable new brickwork and recommend an appropriate brick-cleaning method.

The inspection considers nearby plants, runoff and adjoining surfaces so suitable protection can be planned.
