Quote: perimeter drainage
E.g.: damp basement on the north side
Before requesting a drain around the house, describe where and when water appears and any previous work. Supply plans and photographs where available. The assessment should explain which cause drainage can address and which other moisture sources still need investigation.
Check suitability
Buildwise distinguishes a collector, drainage layer and soil-compatible filter; groundwater requires a specific study. This Belgian technical reference does not establish Luxembourg approvals or a design for your home.
Confirm the discharge point
Before excavation, request a feasible outlet with location, level, capacity and conditions of use. Confirm necessary agreements with operators and authorities. Sewer discharge and on-site infiltration are not freely interchangeable options.
Plan work beside foundations
Define investigations, excavation stability, work sequence and protection of neighbouring services and structures. Identify which sides will be treated and why. Do not select depths or excavation lengths from a generic recipe.
Specify interfaces and handover
Separate drainage, wall protection and waterproofing in the quote. Request installed-system drawings, inspection access, planned checks and maintenance instructions. If pumping is needed, establish servicing requirements and what to do after a failure.
Indicative prices in Luxembourg
On quotation
A rate per metre does not describe the whole project. Request planned lengths and depths, access, protection, discharge and reinstatement. Where pumping is proposed, compare the additional equipment and operating costs separately.
Subsidies and grants
No grant is deducted from the budget shown here. If a quote mentions support, request the exact scheme and confirmation of your eligibility before including it in financing.
Frequently asked questions
Does drainage cure all damp?
No. Request an assessment identifying causes and the expected effect of the proposed system.
Must every side be excavated?
The assessed design determines the extent. Ask why each area is included or excluded.
Can discharge be chosen afterwards?
Confirm a feasible outlet before committing to installation.
When should drains be cleaned?
Request inspection access and instructions for the installed system rather than assuming a universal interval.
