If you have lawns, you will know that they can become compacted with heavy traffic. Also, if you have clay soil, compaction is worse and drainage is a major problem.
The traditional solution is to spike the lawn, and dress it with a light rich soil that works its way into the holes. This, however, is an unexciting process and fails to treat the soil a few inches below the surface.
But wait! Those awfully nice chaps at MaxCo. have - this very minute - invented the MaxCo. Lawn Fracker. This wheel-mounted device carries a large water tank which can be filled, hosewise, to provide weight. Using this weight as a counterforce, the Lawn Fracker then drives a heavy-walled pipe two feet into your lawn. It then injects, under intense pressure, a liquid slurry containing organic matter, gypsum and sand. The pressure drives open cracks in the subsoil, into which the slurry permeates, creating a network of drainage channels and, at the same time, introducing gypsum to remedy the clayiness.
After use, the probe retracts and the whole device can be trundled a few metres away to repeat the process.-- MaxwellBuchanan, Mar 14 2017 A total man-toy ... the Rodinator https://www.youtube...watch?v=uJExdtUEfi8 [normzone, Mar 14 2017] http://www.terraina...e-original-ter.html [hippo, Mar 15 2017] Moles are back, eh ?
//The traditional solution is to spike// the lawn every 10' or so with a quarter charge of C4, a foot'ish down. Tamp, appropriate to a planar effect.-- FlyingToaster, Mar 14 2017 Project Plowshare-- lurch, Mar 14 2017 //Rodinator// But with C4 you don't have to know where the gopher tunnels are. And it makes the ground untunnelable for awhile.
Is clay layered (like slate) ? or just globby.-- FlyingToaster, Mar 15 2017 This kind of already exists - see link for slightly scary-looking machines which will inject your lawn with 280psi air to break up compaction. They use these at Kew Gardens (lots of rare, valuable trees, and also lots of heavy pedestrians compacting the soil).-- hippo, Mar 15 2017 This is a brilliant idea, but I'm in a bad mood [-]-- Voice, Mar 15 2017 This is an idea - I'm brilliant. Okay, maybe just moderately clever, but it's still an idea. I'm not even bad.-- normzone, Mar 15 2017 //This kind of already exists// Wowwwww. Suddenly I want one of those machines. I declare this idea baked.-- MaxwellBuchanan, Mar 15 2017 // Project Plowshare //

ANFO. Drill down, pump in ANFO, drop in a det on a bit of primacord, stem the bore hole and fire the shot. Lovely.-- 8th of 7, Mar 15 2017 ^ "Not what the customer ordered"-- FlyingToaster, Mar 15 2017 random, halfbakery
