Product Description —
Solid Block measuring 240 × 100 × 115mm. Solid (no-cavity) precast concrete block specified at points requiring concentrated load capacity within an otherwise hollow GenBlock wall. Common applications: bearing points for beams or lintels, base of heavy fixings, and fire / acoustic continuity points.
Application
- Non-load-bearing internal partition walls in residential, commercial, and institutional buildings
- Service walls - concealed routing of electrical conduits and plumbing
- Boundary walls in light, non-structural applications
- Internal walls in commercial, residential, and institutional buildings
- Internal columns and pillar construction (GenBrick Pillar, Solid Block)
Key Characteristics
- Multi-cavity profile reduces unit weight and accommodates services routing within the wall
- 115mm standard width fits standard door and window frames without packing or shimming
- Complete connection set - L (left corner), P (right corner), T (junction), U (channel) - for clean wall geometries without on-site cutting
- Flat surface profile reduces skim coat material consumption
- Cavities sized to accommodate electrical conduits and water piping vertically and horizontally
- Wall plugs and proprietary wall anchors can be installed at solid block sections

Installation Notes
- Build walls in stretcher bond using 1:3 cement-sand mortar OR SkimBond thin-bed mortar; joints not exceeding 10mm thick with concave finish
- Limit block work to a maximum of 5 courses per section in any one day
- Coordinate cavity alignment with the M&E contractor before laying so that future utility runs pass through aligned cavities without chasing
- Cure block work for at least 7 days before applying loads or finishes
- Refer to the full Method Statement PDF in the Downloads section for the complete 12-step procedure and GenBlock-specific guidance
FAQ —
What's the difference between GenBlock and traditional Hollow Block?
PBM Hollow Block is the traditional precast masonry unit with two large cavities, used across structural and partition applications including load-bearing walls, lintels, and bond beams. GenBlock is PBM’s improved partition block with multiple smaller cavities – optimised specifically for non-load-bearing internal walls. The multi-cavity profile reduces weight, accommodates utilities piping, and works with SkimBond thin-bed mortar for faster construction. Choose Hollow Block for structural and traditional applications; GenBlock for non-load-bearing internal partitions where ease of installation and finishing efficiency are the priority.
What's the difference between the L, P, T, and U variants?
- L (left corner) — forms a clean external wall corner where the wall turns from one direction to a perpendicular one
- P (right corner / reverse L) — mirrored profile of the L block, used at right-hand corners or in alternating courses to avoid running joints
- T (T-junction) — used where one partition wall meets another at right angles, with structural continuity through the junction
- U (U-channel) — open channel block used for lintels above door / window openings and for bond beams within the wall course, accepting reinforcement bar and concrete fill
What is SkimBond and when should I use it?
SkimBond is a thin-bed mortar adhesive that allows much thinner joints than standard 1:3 cement-sand mortar. It accelerates installation, reduces material waste, and produces a cleaner wall ready for thinner skim coat. Use SkimBond where speed and finish quality are priorities – typically interior partition walls in commercial fit-outs and serviced apartments. Standard mortar remains the default for general construction.
How do I install electrical and plumbing through GenBlock walls?
GenBlock cavities are designed to accommodate vertical and horizontal services runs without subsequent chasing. Coordinate cavity alignment with the M&E contractor before laying – align cavities with intended outlet, switch, and service positions. Where post-installation cuts are needed, use a wet diamond saw and avoid cutting close to load-bearing reveals or jambs. Fill chase channels with mortar or grout flush with the wall face before applying skim coat.
