Years of silt, sand and debris choke drainage capacity and trigger urban flooding. HYVAX restores full flow with hygienic, vacuum-based desilting — no manual scooping, no spillage, no shortcuts. Just open, clean, working drains.
Why Desilting Matters
A drain that looks fine on the surface can be 60% blocked underneath. Sand, grit, organic matter and construction runoff settle and harden over months. The first heavy rain finds out. Regular vacuum desilting keeps capacity at design spec — and keeps streets dry.
01
Restore full hydraulic capacity before monsoon season — turn flood-prone zones back into resilient infrastructure.
02
Vacuum extraction into sealed tanks — no exposed silt, no health risk to workers or the public.
03
Material goes directly from drain to debris tank. No piles on the road, no secondary cleanup required.
04
Municipal stormwater, kerbside drains, culverts, catch basins, and industrial collection systems — all handled.
The Process
Systematic, sectional, and documented — we map the network, work it section by section, and hand back full-capacity infrastructure with photographic evidence.
Stage 01
Inspection of access chambers and outfalls. We assess silt depth, drain condition, and identify any structural issues to flag.
Stage 02
Traffic management deployed where needed. Manhole covers lifted in sequence to control airflow and avoid surge.
Stage 03
Pressurised water is introduced to mobilise compacted silt into a pumpable slurry — gentle enough to leave the drain structure intact.
Stage 04
Slurry is drawn directly into the sealed tank. Visual inspection confirms each section reaches base level before we move on.
Stage 05
Post-clean photos and CCTV (on request) confirm flow capacity. Spoil is transported to licensed disposal — manifest provided.
Where We Work
From municipal stormwater grids to private industrial campuses — same standard everywhere.
