  • The heads and the stones should not be of dumb bell shape.
  • The stone should be dressed properly as per the requirements.
  • A large flat stone should be used under the ends of girders and trusses two uniformly distributed loads.
  • The water which is used in the construction of the stone masonry is of good quality.
  • It is very necessary for to you give your stone masonry e in a proper manner for a period of 2 to 3 weeks after the construction.
  • The plumb bob should be used to check the accurate verticality of the stone masonry walls.

Type of Joints of Stone Masonry

There are different types of joints in the stone masonry which helps to bond with each other.

  1. Butt or Square Joint.
  2. Rebated or Lapped Joint.
  3. Tongued and Grooved Joint.
  4. Cramped Joint.
  5. Tabled or Bed Joint.
  6. Plugged Joint.
  7. Dowelled Joint.
  8. Saddle Joint.
  9. Slate Joint.

1. Butt or Square Joint

Butt or Square Joint

The butt joint is very simple and commonly used to join in the construction of stone masonry work. In the case of butt or square joint, the dressed edge of the two adjacent stones is placed side by side. The two adjacent stones which are placed in this type of joint are abutted with each other.

2. Rebated or Lapped Joint

Rebated or Lapped Joint

The lapped joints are provided in the stone masonry where the movements of the stone units have to be prevented. This type of joint is also known as rebated joints.

The rebates are also provided to prevent the movements of the stones. The length of rebates should not be less than 70 mm. These types of joints are widely used in the construction of earthwork and coping on gables.

3. Tongued and Grooved Joint

Tongued and Grooved Joint

In this type of joint, the stone is made by providing a tongue and a corresponding groove on the adjacent stones. This type of joint is provided to prevent sliding.

4. Cramped Joint

Cramped Joint

In the case of the cramped joint, the holes are provided on the adjacent stones. The cramps are used in this type of joint to connect the stones.

The cramped are the pieces of non-corrosive material whose ends are turned down up to a depth of 4 to 5 cm. The length of the cramp varies from 200 mm to 300 mm. The hole must be cramped with the help of cement water after placing the cramp into its proper location.

5. Tabled or Bed Joint

Tabled or Bed Joint

Tabled joints are used where the lateral pressure is very high and it is necessary to prevent it. In this type of joint, to prevent the lateral pressure at joggle is formed on the upper surface of the bed stone.

Recess is formed on the bottom surface of the stones which laying above the bed stone. The tabled joint is widely used where the lateral pressure is to be prevented such as in the case of sea walls.

6. Plugged Joint

Plugged Joint

The plugged joint is the same as the cramped joint. In this type of joint, the cuts are made in the sites of adjacent stones after arranging the stones in the proper position. This type of joint is widely used for coping and cornices works.

7. Dowelled Joint

Dowelled Joint

In this type of joint a hole is made into each stone and the dowels of small pieces of hard stone or brass are used to connect the stones with the help of cement mortar.

The dowelled joint is used to prevent the adjacent stones against displacement or sliding. The thickness of the dowels is used of 5 cm and 10 to 15 cm long. This types of joints prevent unwanted displacement of these stones.

8. Saddle Joint

Saddle Joint

A saddle joint is provided to protect the joints in the cornices. This type of joint is also known as a water joint. Saddle joints are used in the cornices and other weather surfaces to divert the water away from the joint.

9. Slate Joint

Slate Joint

In this type of joint grooves are made on the sides of the surface of the adjacent stones. A piece of Slate is placed between the gross of the adjacent stones.
