Bluestone Patio Installation in MA

Bluestone patio installation is a favorite choice among homeowners for natural stone patios in MA.  Bluestone is a type of sedimentary stone common to the New York/Pennsylvania area.  As a sedimentary stone, bluestone is formed in layers deep below the earth’s surface.  As bluestone is quarried the naturally occurring layers make it great for producing wide, flat, patio stones.

Bluestone is readily available in New England and is the go-to choice for classic, natural stone patios.  It is attractive with subtle blue/gray/purple hues, quick to install, and durable.   There are a variety of different types of bluestone patios to choose from.  Whatever variety you choose it is sure to look great and last a lifetime.

Bluestone Patio Installation Process:

The bluestone patio installation process is fairly straightforward but does take a lot of attention to detail and hard work.  The process starts by first excavating an adequate base.  The base depth will depend on the existing soils but is usually ~8-10″.   Essentially the goal is to remove all of the organic soils that will hold moisture, and reach the firmly packed, well drained, sandy/stoney subsoils below.   

Once we have removed all undesirable soils we compact the subsoil, and then lay our base material.  The base material will consist of crushed stone that gets spread in 4″ increments, and compacted.   Compacting it every 4″ ensures proper compaction of the base so that your patio doesn’t settle. 

After the base material is compacted we spread a 1″ layer of finer crushed stone or sand.  This layer of finer material is much more workable in that we can spread it perfectly flat, and set our stones in it.  When spreading the bedding layer we pay close attention to pitch so the patio has a minimum 1% pitch for drainage.   This ensures that water will runoff the patio instead of puddling and working it’s way underneath.

Next we lay the patio stones.  Although bluestone is cut or split to a somewhat consistent thickness, it is a natural stone and will vary.  As we lay each stone it is often necessary to make slight adjustments to the bedding layer so that there are no lips or differences in height between two stones.  This ensures a nice, smooth patio that you won’t catch a toe or snow shovel on.  Once all the stones are down we then go through and adjust the joints.  Again each stone is supposed to be cut to a certain size from the quarry, but, there are inconsistencies.  In order for all the joints to be consistent in size and appearance we will go through and nudge the stones with a prybar to hide any differences, and/or cut the stones in place when needed.

Finally once all the stones are in place and the joints are cut we spread the joint material and secure the edge.  A plastic edging strip will get staked into the ground with steel stakes.  This ensures the edge stones don’t tip or migrate over time.  For the joints we sweep in the same bedding material, or, a special polymeric sand that looks like sand, but hardens up like a firm rubber.  This polymer sand is meant to discourage weeds and insects from coming through the patio joints.
