RIG MANIFEST & CALIBRATION

Calibrated industrial pumps and chemical injectors deliver verifiable water pressure without gouging masonry surfaces.

Standard consumer pressure washers blast uncontrolled streams that carve trenches into brick faces and shatter mortar joints. Our trailer-mounted commercial units isolate volume from velocity, running industrial triplex pumps capable of 1500 to 4000 PSI alongside dedicated low-pressure soft wash proportioners operating below 100 PSI.

PUMPING MACHINERY

Commercial triplex plunger pumps engineered for continuous duty and calibrated unloader valve control.

HIGH-PRESSURE SYSTEM Belt-driven industrial triplex plunger pump generating 1500 to 4000 PSI at 5.5 to 8.0 GPM water volume.
PRESSURE REGULATION External trapped-pressure unloader valve routed back to supply buffer tank, eliminating heat buildup during trigger closure.
LOW-PRESSURE SYSTEM Air-diaphragm and 12-volt chemical delivery pumps delivering 45 to 85 PSI at up to 6.0 GPM for mortar-safe biocide application.
MANIFOLD MONITORING Stainless liquid-filled glycerin pressure gauges calibrated in 100 PSI increments for continuous pressure verification.
SERVICE RATES $0.15–$0.50 / sq ft for high-pressure brick washing; $0.15–$0.30 / sq ft for chemical soft wash; minimum trip charge $150.

SPRAY NOZZLE PROFILES

Nozzle orifice diameter and spray pattern determine surface impact force. A narrow fan at high pressure destroys brick; a wide calibrated fan cleans without abrasion.

0-DEGREE RED TIP PROHIBITED ON BRICK. Zero-degree solid pin-stream generates destructive hydraulic shearing. Never deployed on clay or lime mortar assemblies.
15-DEGREE YELLOW TIP Restricted strictly to unpainted industrial steel containment curbs and heavy unmortared paving units. Excluded from all vertical wall assemblies.
25-DEGREE GREEN TIP Dense vitrified clinker brick and hard modern Portland cement joint surfaces with heavy atmospheric carbon buildup.
40-DEGREE WHITE TIP Standard high-pressure washing nozzle. Disperses water stream over wide impact swath to prevent face gouging and aggregate dislodgement.
LOW-PRESSURE BRASS TIP Large-orifice chemical fan nozzles operating at <100 PSI, applying detergent foam without mechanical impact to sensitive lime joints.

CHEMICAL PROPORTIONING & DELIVERY

Atmospheric soot and biological colonisation dissolve through precise chemical balance, eliminating the need for brute surface blasting.

DOWNSTREAM INJECTION Stainless injectors introduce cleaning chemistry after the high-pressure pump, preventing corrosive detergent contact with internal pump valves.
PROPORTIONER VALVES Metered chemical manifolds permit instant adjustments from 1% to 6% active biocidal concentration matched to biological spore density.
DELIVERY LINES 200-foot commercial chemical-resistant hose runs equipped with brass and stainless steel valved couplers, eliminating high-pressure pulsing.
RUNOFF MANAGEMENT Geotextile filtration booms and non-permeable rubber berms redirect wash wastewater away from sensitive landscaping and public storm drains.
Braided steel pressure wash hose lines and brass quick-connect couplers laid across exterior walkway
