Wembley has two very different kinds of drainage side by side: interwar semis on original clay, and large new-build developments around Wembley Park.
Most of residential Wembley went up between the wars, when the Metropolitan Railway pushed suburban building out along this corridor. Those 1930s semis were built on clay drainage with the usual mortar joints, and they now sit on ground that moves. Much of the area sits on London clay, which shrinks in dry summers and swells again in winter, and old drainage moves with it. Cracked and displaced joints are common, and problems often show up after a long dry summer.
Wembley Park is a completely different proposition. The newer residential towers around the stadium run modern plastic and pumped systems serving many flats, with communal risers, basement plant and attenuation for surface water. When something fails in a building like that it can affect many households at once. The commercial side here is shaped by the stadium and the arena: food businesses around Wembley Park and along the High Road can be far busier on event days, and grease management sized for a normal week may not cope with a sell-out event, which is where planned commercial drainage maintenance helps.
Clay movement can crack and displace joints in interwar drains, often after a dry summer.
A single fault affects many flats. Needs coordinating through the managing agent rather than flat by flat.
Event days can overwhelm grease management sized for an ordinary week.

Call and speak to the engineer. 24 hours a day, including tonight.
Sinks, toilets, gullies and main drains cleared, with the cause identified rather than guessed.
Overflowing gullies and blocked manholes or inspection chambers, cleared and explained.
Toilets that will not flush, or that fill up and will not drain, cleared without damaging the pan or the soil pipe.
Kitchen sinks and waste pipes blocked with grease, cleared properly rather than just poked through.
Standing water in the bath or shower tray, and slow bathroom basins, cleared at the cause.
Sewage backing up, drains overflowing, or a home or business you cannot use until it is fixed. Phone answered 24/7.
Scours grease, silt, scale and roots off the pipe wall, rather than just making a hole through the blockage.
See the inside of the pipe: recurring blockages, pre-purchase checks, insurance and subsidence claims.
Cracked joints, root damage and collapsed sections, repaired without digging where the pipe allows.
Restaurants, pubs, offices, landlords and managing agents: planned maintenance and out-of-hours call-outs.
Leaks, taps, traps, toilet cisterns and waste pipes: the plumbing that often comes with a drainage job.
Common questions about drainage in Wembley, answered for the kind of property you find there.
Probably not. Clay soil shrinks in a dry summer and swells again through winter, and drainage laid in the 1930s gets flexed by that cycle every year. A long dry spell opens joints and cracks sections, and the blockages show up in the following months.
By sizing your grease management for your busiest day rather than your average one, and by timing planned jetting around the fixture list. A trap that copes with an ordinary week will not cope with a sold-out event, and losing a trading day on a big event usually costs far more than jetting the line beforehand.
