Rockbreak Expanding Mortar
Non-explosive demolition agent — cracks rock and concrete silently from drilled holes.
Pack sizes on request
In stock: Windhoek & Walvis Bay
The last 5% of every Namibian project comes off our miscellaneous shelf: manhole covers for the services, expanding mortar where rock met the trench line, paraffin and cotton waste for the finishing trades, WD-40 in the site box, silica gel in the electrical panels. Swachem is where the QS sends someone at 7am — and where the genuinely odd requirement gets sourced rather than shrugged at.
Load-rated covers are supplied against stated duty classes; Rockbreak carries application and safety documentation for method statements.
Order manhole covers when the civils start, not when the finishes do — sizes and duty classes that are shelf stock in March are a three-week wait when four projects hit practical completion together in November.
The lines construction buyers draw from this category most.

Drill the pattern, mix, pour, and let expansion pressure crack the rock silently over hours — no licence, no vibration claims from the neighbours, no fly-rock. Hole diameter, spacing and temperature drive success, so take the guidance sheet seriously, and never inspect a charged hole from directly above. For serviced-plot boulders it has effectively replaced blasting.
Polymer covers and frames across the standard sizes and duty ratings — the modern spec for services work, lighter to install than cast iron and worthless to metal thieves, which in Namibian municipalities is a genuine selection criterion. Match the duty rating to the traffic case and the municipality’s standard; we will confirm against your services schedule.
The recurring basket: cotton waste for the painters, paraffin for glass cutting and clean-up, sugar soap for pre-paint washdown, WD-40 for everything that sticks, brushes and rollers by the box. One weekly order from one counter replaces four small-supplier runs — which on a programme-driven site is foreman time recovered.
Panels and equipment installed months before power-on sit through humid coastal nights or rain-season air collecting condensation — silica gel sachets in DB boards, control panels and stored equipment absorb that moisture cheaply. Coastal contractors treat it as standard practice; the alternative is commissioning-day corrosion surprises.
