FAQ
Practical answers about dam linings, steel water tanks and waterproofing services.
Yes. We supply materials and install with our teams, or coordinate with your earthworks contractor on dam projects. Single point of contact reduces gaps between civils and lining work.
We work across South Africa with strong presence in Gauteng, Limpopo, Mpumalanga and the Western Cape. Remote sites are quoted with travel and mobilisation included.
Often yes. Many clients store bulk water in a lined earth dam and pressurised or clean water in a steel reservoir. We design both sides of that system.
Qualifying materials supplied by Damtech may carry a supplier-backed material warranty of up to 10 years where stated in the project quotation and subject to the relevant supplier’s terms and conditions. Damtech’s workmanship warranty is 12 months from practical completion unless a different period is stated in writing for the specific project. Warranty coverage, exclusions and maintenance requirements are confirmed in the applicable quotation or contract.
Often yes, if damage is localised and the liner is otherwise sound. We patch HDPE, repair torch-on sections or recommend relining when UV degradation or widespread failure makes patching uneconomical.
Yes. Steel tanks receive PVC lining as standard; concrete and cement dams may use bitumen torch-on or HDPE depending on structure and use. See our reservoir lining page for options.
