Additional kiln-dried sand should be brushed-in as required. The first of the linked sub-pages in this section considers the use of Modified Mortars and of polymeric sand , which is best thought of as a special sand that is chemically 'glued together'. Please read Email FAQ before sendingemails, questions, photos, etc. As was mentioned earlier, this method of jointing is a useful technique on pavements that have a few loose elements, as the slurry seeps into places a normal mortar would never reach, filling voids and replacing lost bedding, and, hopefully, stabilising the pavement without having to undertake a complete "lift and re-lay" exercise. The method relies on making a mortar slurry, ie, a very, very wet mix, with the consistency of a hearty pea soup. We Partner with Only the Best Manufacturers. This is the most common method used for sealing the joints between flags/slabs. An alternative strategy utilises a pure kiln-dried sand, and is typically reserved for flexible block paving , small element paving and some decorative patio flags/slabs. Additional sand, needed to top-up any 'hungry' joints, can be spread over the surface following consolidation. It is also a useful technique for re-jointing an existing pavement that has several units that 'rock' or 'wobble' when trafficked. Joints sand level, must be at least 1/8 inch (3 mm) below top of paver’s surface or 1/8 inch (3 mm) below the chamfer. Call the professionals at Peach Country Tractor! The further page looks at some of the more unusual or esoteric other materials that can be used for jointing special paving or for designer paving. The further page looks at some of the more unusual or esoteric other materials that can be used for jointing special paving or for designer paving.

We use a wide-headed soft brush to spread the sand and chase it into the joints. The ductile iron used to manufacture the pipe is characterized by the spheroidal or nodular nature of the graphite within the iron. Choosing a selection results in a full page refresh. Pack down the mortar with the edge of the pointing trowel until the section of joint is filled. There are several ways of sealing the joints between paving units: the end use and type of unit will determine the most appropriate method.

Repeat steps 1 and 2 to ensure joints are filled and consolidated. The sand to be used consists of grains that fall within an upper and lower size range, to ensure maximum interlock between grains. Need to get the job done? However, there is an issue using this strategy with some jointing sands, because the grains can be crushed onto the surface of the blocks which can result in a near-permanent 'spot' stain, and so it is usually recommended that surplus sand is removed prior to consolidation to avoid just this problem. It should be protected from foot or vehicle traffic for at least 48 hours. Obviously, a vibrating plate compactor isn't suitable for use with most patio flags and so we have to rely on gravity and foot traffic to settle the jointing sand. When it comes to tractors, we at Peach Country Tractors have more than three decades of experience. Virtual joints and multiple sizes allow for a seamless connection between units. We rent: Tractor Attachments, Backhoes, Front End Loaders, Skid Loaders, Tractors, etc. In hot weather, the area can be hosed down, or left to dry in the sun, as long as the brushing continues more or less non-stop. It is less satisfactory when the flags are dry- or butt-jointed, as the dry mixture does not to bond to the edges of the joints. One step to total moisture mitigation - saves time and labor.

The polymer modified sand hardens as it dries. Alternatively, the mortar can be 'polished' with a rounded, or even a V-shaped, pointing bar, which can be fashioned from a short length of copper tube. On most flagging projects, it is a easy way to seal the paving effectively and keep the surface staining to a minimum, as long as the joints were buttered and the mortar used to butter the joints is still relatively fresh (less than an hour old).

This mortar should start setting within 2 hours, faster in summer, slower in winter. The mortar should be a Class II and made up in advance as shown on the mortars page. There are two sets of weather conditions that suit this method of sealing; damp or wet weather, and baking hot days. The pointing will 'top-up' the buttered mortar to form a solid mass with no day joint between butter mortar and pointing mortar. It should be just damp enough so that it clumps into a ball when compressed in the hand, but no water should dribble out between the fingers. See also: Loose fill jointing for Stone Pavements. Williamstown (856) 226-3834 Contact Us. Click here for a case study illustrating the pointing of a flagstone patio using a coloured mortar. This is a variation on the wet grouting method described above, and can only be carried out when the surface of the paving is perfectly dry. All of our storage units are Outside Drive Up Storage units. It is also recommended for surfaces exposed to heavy traffic, and for high-humidity areas. If the "allow to dry" option is taken, repeated brushing ensures that no thickness of mortar is permitted to build up and 'adhere' to the paving, and any surplus gradually turns to dust, which is best removed by changing to a soft brush and sweeping again. It is also used for rigid block paving and for pointing the joints that occur between sectional kerbs and edging units. The 'wetness' of a mortar or concrete is properly referred to as its "slump" and most mortars have a low slump value, often 20mm or less, ie, they are fairly 'stiff'. You are strongly advised to seek professional, onsite advice for your project. Make sure the paving is dry on the surface before commencing the mortar work, as very damp or wet paving is more likely to stain. All sand joints, regardless of type of paving, should be checked after 4-6 weeks, as there is always some slight settlement that results in a small number of empty or partially-empty joints. At one time, it was thought that striking a mortar joint was purely cosmetic, but it is now known that the striking action helps harden the mortar and make it less susceptible to frost or water damage. This slurry is brushed over the paving and into the joints. After 3-6 months, the sand will seal itself with detritus on the surface and become almost impermeable. This is what is normally referred to as "Mortar Pointing" or rigid pointing. By hosing down the flags a few hours before pointing, it quenches their thirst and gives the mortar a better chance. This section has been moved to this page, 32, Newchurch Lane Culcheth, Nr. High Moisture Technology. Allow the mortar to become quite dry, say 1 hour or thereabouts on a fine, but not hot, day.

Sweeping at an angle of 45° to the direction of the paving joints prevents the mix from being swept out of the joint. Collect up the sweepings and dispose. Once hardened, it will resist joint wash-out, lock in paver sand and reduce weed growth. This type of pipe is a direct development of earlier cast iron pipe, which it has superseded. However, it should be noted that because such a large quantity of water is used with this method of jointing, the strength of the mortar will be adversely affected.
