Installation Details for Kerb & Edgings
INSTALLATION DETAILS FOR KERB & EDGINGS Health and Safety Information Safe working practices should be employed at all times during the construction process and all necessary Personal Protective Equipment (PPE) should be worn. Drainage All paved surfaces require drainage. Where kerbs or edging are laid, this will restrict natural water flow off the paved area, so provision needs to be made to dispose of this water. This can be in the form of using cross fall and longitudinal fall to run water into areas of soft landscaping (i.e. a flowerbed or grassed area). However, where this is not possible, some form of drainage channel will need to be utilised. If laying kerbs or edgings next to a building, then care should be taken that the laid products are at least 150mm below the damp proof course level. Excavation To allow new kerb or edging to be installed correctly a certain amount of excavation will normally be required. The depth of this excavation will depend on several factors; the height of the kerb or edging selected, which way up it will be laid, and what upstand is intended. (i.e. the difference in height between the top of the kerb or edging and the paved surface in front of it). All organic materials such as grass should be removed from the excavation as this will rot and could cause possible settlement of the kerbs or edging and paving at a later stage. When the desired level has been reached the bottom of the excavation should be compacted to give an even surface. -

A Masonry Wall and Slide Repair Using Soil Nails and Rock Dowels Drew Gelfenbein, Christopher Benda, PE and Peter Ingraham, PE 1.0 Background
A Masonry Wall and Slide Repair Using Soil Nails and Rock Dowels Drew Gelfenbein, Christopher Benda, PE and Peter Ingraham, PE 1.0 Background In the middle of August 2003, Vermont experienced several days of very heavy rains which precipitated a slide failure on Vermont Route 73 in Forest Dale at approximately mile marker 6.36. A blocked culvert on the south side of VT 73 caused an overflow of water across the road surface and over an asphalt and wood curb down an embankment. This resulted in a significant amount of erosion, undermining of the road surface (Figure 1) and a washout of a timber cribbing retaining structure Figure 1: Undermining of north side of VT 73 located on the top of a mortared masonry wall (Figure 2). in Forest Dale. In the project area, VT 73 is constructed on a retained embankment in steep terrain formed in sub-vertically dipping schistose meta-greywacke. The embankment along a valley sidewall was originally built by constructing masonry retaining structures to span between a series of rock knobs. Soils mantling the rock in the valley consist of dense glacial till. The natural terrain was incised by the Neshobe River, which occupies the valley floor approximately 80 feet below and 100 feet north of the project retaining walls. After site visits by Vermont Agency of Transportation (VTrans) staff, it was decided that the laid up masonry wall immediately west of the slide area was also in desperate need of repair. The laid up masonry wall (Figure 3) was observed to have broken and missing blocks. -

The Art of Stone Masonry in the Rockbridge County Area (1700 to Present)
The Art of Stone Masonry In the Rockbridge County Area (1700 to present) Steven Connett Archaeology 377 5/25/83 Dr. McDaniel The art of stone masonry in the Shenandoah valley seems to be somewhat of a mystery prior to the nineteenth century. However, as some of us have learned from the anthropology 101 course: The absence of artifacts (documents in this case) is just as important as the presence of artifacts. In order to make sure that the lack of information was not due to my possible incompetence in research, I spoke with a current day stone masoner named Alvis Reynolds. Mr. Reynolds relayed t o me that when he was trying to learn the skills of stone masonry he, too, had great difficulty in obtaining information and thus decided to teach himself this art through the process of trial and error. Although this information did not directly aid me in my research, Mr. Reynolds did provide me with a bit of information that allowed me to derive a hypothesis on why there is this unusual lack of information in this line of study. I will state my hypothesis in this paper, however, I will not be able to prove it or disprove it due to the deficiency in available information. Mr. Reynolds explained to me that in the eighteenth century there were nomadic stone masoners. These nomadic workers went from valley to valley in search of people who needed help with building their houses. Since these people did not know how to cut stone themselves (after all, stone cutting is not the type of thing that is innate to most people) they had no choice but to p~y these men for their services or go unsheltered. -
Field Stone Quarrying
Field Stone Quarrying The depression in front of you contains the remains of a field stone quarrying site. The early settlers of this area typically used existing field stones to build rock walls, dry laid foundations for buildings, and small mill dams. When the rocks were too large to move, or for their intended use, they were split using hand tools. The usual splitting process used a series of wedges along the intended crack direction. The wedges were typically fashioned of steel by a blacksmith who then hardened them through quenching and tempering. Steel was expensive at the time but the typical wrought iron that a blacksmith used was much too soft to serve as a rock splitting wedge. The wedges were of two types, those to be used in rectangular holes and those for round holes. Rectangular holes were made in the rock using a cape chisel and cylindrical holes made with a plug or a star drill. The cape chisel was pounded with a hammer to create a rectangular hole. The plug drill (2 cutting edges) or star drill (4 cutting edges) were rotated slightly between each hammer blow to break up a new surface at the bottom of the hole. During the process, the drill was pulled out and the hole was cleared of rock Top to bottom: Cape chisel, plug drill, star drill. dust, typically by blowing through a small tube inserted in the hole. In the case of the round hole, the wedge was inserted between two semi-cylindrical tapered inverted wedges (“feathers”) in a hole drilled by hand in the rock. -
TIPS for MIXING MORTAR for MASONRY Masonry Cement Is Basically Normal Portland Cement with Ingredients to Provide the Plasticity Required for Masonry Work
TIPS FOR MIXING MORTAR FOR MASONRY Masonry Cement is basically normal Portland cement with ingredients to provide the plasticity required for masonry work. Masonry cements are pre-packaged as either Type N Masonry Cement or Type S Masonry Cement. Type N Masonry mortar is recommended for general use in non-load bearing walls as well as in exterior veneer walls not requiring high strength. Type S Masonry mortar is recommended for use in all masonry be- low grade as well as in exterior load bearing walls requiring high strength. Type N Masonry Cement or Type S Masonry Cement can also be used in parging and stucco work. DO NOT use masonry cements for concrete jobs. Masonry cements are mixed with sand in the following proportions (by volume).: 1 part Type N or Type S Masonry Cement 3 parts damp, loose brick sand Mix the cement and sand. Add water until the mortar is of suit- able “buttery” consistency. One bag of masonry cement is required to lay 35-40 blocks or 135 bricks. Caution: Freshly mixed cement, mortar, concrete, or grout may cause skin injury. Avoid contact with skin whenever possible and wash ex- posed skin areas promptly with water. If any cement or cement mix- tures get into the eyes, rinse immediately and repeatedly with water and get prompt medical attention. Keep children away from cement powder and all freshly mixed cement products. This publication is intended for general information purposes only.
