Paver Installation in Kirkland

For a surface you intend to use rather than merely cross, gentler than most people assume. A walk can carry a noticeable grade comfortably; a terrace where you want a table and chairs cannot, because furniture and people both need something close to level. Beyond a modest grade the honest options are to terrace the slope into levels connected by steps, or to accept it as a route rather than a room. Where a slope is genuinely steep, there is also a stability question that comes before the paving one — adding load above a slope and changing where water goes are the two mechanisms that turn stable ground into moving ground, and both are things a hard surface does.

Because the restraint at the bottom edge was specified as an edging rather than as a structural element, and on a grade those are different jobs. Every unit on a slope is pushing on the one below it, and the whole field is bearing on whatever is at the low end. A plastic edging pinned into base rock will hold a flat patio indefinitely and will gradually lose an argument with a sloped one. The fix is a proper restraint at the low edge — a concrete haunch, a laid kerb or a low wall — and, where the movement has already opened joints at the top, lifting and resetting the units back up to their original line.

That depends on what is between you and it, and it is the question to resolve first on a downhill lot. Falling toward the lake is not by itself a discharge route; the water still has to reach somewhere it is entitled to go without crossing a neighbour or undermining anything on the way. Frequently the honest answer on these lots is a piped run to a legitimate point rather than allowing surface flow to find its own way, because uncontrolled sheet flow down a grade concentrates and erodes. On properties near the shoreline there are additional constraints on what can be discharged and where, which we confirm for your address rather than assuming.

They should be, and separating them is a common cause of the uneven risers people live with for years. Steps and the surfaces either side of them are one levels problem — riser height depends on where each paved level finishes, and paving laid first to a level that was not set with the steps in mind produces a first or last riser that is out of step with the rest. Built together, the run is set out as a whole, every riser matches, and the transitions at top and bottom land flush. It is also cheaper as one job than as two visits, because the setting out is done once.
