Drainage concerns collecting and conveying unwanted water. Waterproofing concerns limiting water passage through building elements. The two address different functions and are not interchangeable.
In this article
Requesting “drainage work” does not define a solution. Rain-related ponding, water in the ground and moisture around a building are different observations. Identify what is known before requesting a particular method.
Separate the functions
Managing water movement and protecting a building element from water passage are different tasks. A project may need both. Completing one does not automatically remove the need to assess the other.
Record the circumstances
Note when the issue appears, the affected areas and whether it follows rainfall. Dated photographs help explain the situation. These observations support professional assessment; they do not establish a technical diagnosis.
Compare a defined scope
Ask what evidence the proposal relies on, which preparation and reinstatement works are included, how connection conditions are addressed and what records will be delivered. Share drawings and information on previous interventions where available.
Consider future access
Discuss inspection and maintenance access early. Product literature and generic details cannot establish a suitable solution for a particular building. The objective is an evidence-based assessment, followed by a clearly documented scope.
Frequently asked questions
Does drainage replace waterproofing?
They perform different functions. A project-specific assessment determines whether and how both are needed.
Is one method suitable for every site?
No. The source of water, site conditions and existing systems vary.
