Hollowblocks
Hollowblocks: free seamless stone PBR material with albedo, normal, roughness, metalness, height, AO maps. CC0 licensed.
Crafted from the prompt: "Overall look
A raw, gray concrete wall made of stacked concrete hollow blocks (CHB), the standard building material in Philippine homes, fences, and boundary walls. It has never been plastered, skimmed, or painted, so the bare structure is exposed.
Blocks and surface
The blocks are rough, sandy-gray, and slightly uneven in tone. Some look lighter and chalky, others darker and damp-stained.
The surface is pitted and grainy, with small air holes, chipped corners, and crumbly edges where blocks were handled or cut.
A few blocks show hairline cracks or small broken corners.
Mortar joints
Thick, uneven mortar lines of 1 to 2 cm run between the blocks. They are not neatly tooled, and some bulge out or smear over the block faces.
Dried mortar splatters and drips cling to the wall, with a few gray streaks running downward.
Some joints are slightly misaligned, so the courses (rows) wobble a little instead of running perfectly straight.
Signs of unfinished work
Rebar stubs (rusty steel bars) poking out of the top or side, where a column or the next floor is planned.
The top row is jagged, with half blocks or gaps, as if building paused midway.
Wooden scraps, a leftover mixing board, or a pile of sand and gravel at the base.
Patches of grout or “concrete slurry” where hollow cores were filled.
Sometimes a strip of exposed concrete column or tie beam beside the blocks, also unfinished.
Weathering
Dusty white efflorescence (salt deposits) in patches.
Dark water stains, moss, or grime near the bottom from rain splash.
Rust-orange streaks beneath any exposed metal.
Atmosphere
It looks like a typical Philippine construction site or a house “pa-extend” in progress: practical and honest, with the plaster and paint still waiting for the budget to catch up."
