Tarmac & Asphalt suits Hilsea well, given a mix of interwar semis and post-war housing, with the historic Hilsea Lines fortifications nearby; in practice that means hot-rolled asphalt compacted over a prepared sub-base into a single dense, flat surface. What that means on the ground in Hilsea is wider interwar frontages than the terraces further south, generally easier for off-street conversion, and proximity to the historic Hilsea Lines moat and generally low-lying northern Portsea Island ground. Where it earns its keep is larger driveways that can achieve a proper fall to a drainage point; the honest caveat is that standard tarmac is impermeable, so the drainage fall has to be built in at construction.
About Tarmac & Asphalt
Tarmac and asphalt driveways are formed from hot-rolled bitumen-bound aggregate, laid in one or two courses over a compacted stone sub-base and rolled while still hot to bond into a single dense, flat surface. It is quick to lay across a large area compared with unit-by-unit systems, copes well with sustained vehicle weight, and gives a classic, understated dark finish that suits both period and modern properties without competing with the architecture. Standard tarmac is not permeable, so correct falls and edge drainage need to be built in at construction rather than added afterward, and a sound, well-compacted sub-base is what actually determines how long the surface lasts rather than the tarmac layer alone.
Best suited to: larger driveways, properties wanting a low-fuss uniform finish, and sites that can achieve proper falls to a drainage point
Less suited to: sites with no viable drainage fall or where a permeable/SuDS-compliant surface is specifically wanted
Ground & property in Hilsea
Hilsea sits at the northern tip of Portsea Island around the historic Hilsea Lines fortifications and moat, on ground that stays low-lying this close to the water. The housing mix here is interwar semis alongside later post-war development, and the frontages are generally wider than the terraces further south, making off-street conversion comparatively straightforward once drainage is accounted for.
