Whether you are executing a structural basement underpinning project in Moor Park, casting an insulated ground slab in Northwood Hills, pouring a commercial-grade yard in Rickmansworth, or laying foundations for a luxury extension in Pinner or Ruislip, Ready Mixed Concrete Northwood manufactures compliant, British Standard concrete right on site.
Designated & Designed Concrete Grades (BS EN 206 & BS 8500)
Our computerized volumetric mixing systems carry clean graded aggregates, sand, and Portland cement in distinct bins. Review our core mix formulations:
| Mix Grade | 28-Day Strength | Structural Applications & Performance |
|---|---|---|
| GEN 1 / C10 | 10 N/mm² | Site blinding layers, trench stabilization, drainage pipe bedding, non-structural curb haunching. |
| GEN 2 / C15 | 15 N/mm² | Unreinforced strip foundations for garden boundary walls, greenhouse slabs, domestic terrace sub-bases. |
| GEN 3 / C20 | 20 N/mm² | Internal garage slabs, garden workshops, shed bases, domestic internal flooring without heavy structural mesh. |
| FND 2 / C25 | 25 N/mm² | House extension trench fill, underpinning pins, structural ground-bearing slabs, ground beams. |
| PAV 1 / C30 | 30 N/mm² | Outdoor vehicular driveways, commercial yards, heavy patio slabs, freeze-thaw air-entrained pavement. |
| PAV 2 / C35 - C40 | 35-40 N/mm² | Heavy industrial plant hardstandings, waterproof basement retaining walls, suspended structural slabs. |
Why Northwood Contractors Mandate Volumetric Batching
Eliminates Under-Ordering Risk
Unforeseen soft ground, gravel layers, and variable trench depths are common across Northwood, Three Rivers, and Hertfordshire developments. With our mobile trucks, if you need 0.5m³ to 2m³ extra, we batch it immediately without a second callout fee.
Zero Unused Disposal Charges
Traditional drum mixer suppliers charge steep penalties to take back surplus concrete. With volumetric batching, mixing stops the instant your timber forms are filled — ensuring zero financial waste.
Live Slump Adjustment
Tightly packed steel reinforcement rebar cages require high-slump flowable concrete, whereas sloping ground demands stiffer mixes. We adjust workability on-site with calibrated digital controls.
