THIN FLATS: Thin flat New England fieldstone is a great fit for shorter walls. Even this smaller wall is just enough to retain lawn and garden areas from the main sidewalk. Thin flats allow the details of smaller stone wall design to stand out.
One thing to remember with thin New England fieldstone is that the top usually consists of many small pieces, which leads to a high chance of mortar cracking, or even pieces falling out. Installing a solid cap not only helps frame the stone wall visually, but also to eliminate exposure of all top joints.
MEDIUM FLATS: Medium flats can be used for larger areas and can support higher walls. Dry laid walls will allow water to pass through the wall, avoiding pressure buildup. But if a mortared style is preferred, additional drainage measures must be designed to avoid water buildup which could damage a wall and surrounding plant material.
Quality of stone wall construction depends on the craftsmanship and the quality of stone. A mix of sizes can lead to a less appealing wall (below) with different size gaps and uneven stone orientation.
But uniform sizing and quality stone allows for solid stone wall construction with stunning effects.
LARGE FLATS: Large flat fieldstone can be used in the landscape as walls as well as incorporated into steps. Consistent use of stone products for stairs and walls can soften the formality of a design.
By using large fieldstone steppers similar to the wall stone, stairs almost disappear. If a contrasting stone such as granite was used, your eyes would immediately be drawn to the stairs. This is a great way to blend the stonework with the surrounding landscape.
IRREGULAR STONE: A well constructed irregular stone wall will have even sized joints, 2 over 1 stacking and sizing from top to bottom. If the irregular stone is a little more rounded and has slightly larger gaps between the stones, gaps should be similar in spacing which will present a uniform look to the wall.
