Lagoon Construction & HDPE Lining – Built to ADM Standards

At Lasani General Contracting, we design and build lagoons for industrial, agricultural and municipal clients across Abu Dhabi. We cover the whole job, from site preparation to the final liner test.

What we deliver
1. Site preparation & excavation: we clear and level the site and dig the lagoon floor to the depth in the design.
2. Engineered bund walls: we build sand bunds with stable side slopes and a set crest width, compacted in layers so they stay strong over time.
3. Sand supply & logistics: we arrange the sand, either collected and moved within the same industrial zone or brought in from approved outside sources. We plan quantities to allow for compaction, so the job doesn't run short.
4. HDPE geomembrane lining: we supply and install 1.5 mm HDPE liner, welded by heat fusion and fixed in anchor trenches. Where the design calls for it, we line only the bund boundaries, so you don't pay for liner you don't need.
5. Quality testing: we test every welded seam before handover.
6. ADM compliance: all design and construction follows Abu Dhabi Municipality standards.

Why clients choose us

1. One contractor, one point of contact: excavation, earthworks, sand and liner all come from us, with no handover gaps between subcontractors.
2. Several sites at once: we can mobilise to multiple locations at the same time and deliver consistent quality on each.
3. Clear pricing: we price each lagoon separately, with sand as its own line item, so you can see exactly what you're paying for.
4. Practical engineering: we size bunds, slopes and liner coverage to suit the site, which keeps costs efficient without cutting corners.
