Evaluation trial trenching by S P Dyer for SCAU and Alchemy Ltd located no features or stratigraphy but recovered one sherd of IA date and pottery and tile of Romano-British and medieval date.

Evaluation by trial trenching in advance of construction of the M25 service station, by Graham Hayman of SCAU for the Department of Transport, revealed concentrations of 13th century pottery associated with areas of burning, thought to indicate the production of Limpsfield ware; further excavation was recommended. Two sections, one either side of the M25, were also dug through the London-Lewes Roman road and variations in construction were noted. Two areas, one either side of the motorway, were subsequently excavated by Graham Hayman of SCAU for English Heritage.

Two seasons of excavation were directed by G H Cole for SHAHT. There was evidence for earlier prehistoric occupation (worked flints) and late Iron Age occupation and possibly related iron working (pottery and slag). Parts of possible buildings of the 2nd/3rd centuries were identified and there was late RB material including part of a jet finger ring with a monogrammed cross. No evidence was found for medieval occupation but the site had evidence for a post-medieval tanning industry known from documents to date c l596-1851.

A watching brief on groundworks at the Town Hall and some excavation was carried out by P M G Jones of SCAU for Spelthorne Borough Council. This confirmed that the building lay over medieval and Roman near-shore muds and silts which were sealed below 16th-17th century levels, probably representing foreshore reclamation. A reed peat filled feature of 15th century date was recorded, which contained numerous cut offs of wood and scraps of leather. The earliest buildings on the site appear to be late 15th or 16th century in date.

Evaluation by trial trenching in advance of gravel extraction, by Graham Hayman of SCAU for Hall Aggregates Ltd, adjacent to an area where work in 1989/90 had revealed Bronze Age and Roman features, revealed more extensive features, indicating occupation of mid-late Iron Age to 4th century date, with some evidence from the Bronze Age.

Test excavation some years previously by R Masefield of a possible RB tile production site located a large pit feature filled with 550 fragments of RB tile. They included much waster material represented by partially fired, overfired and distorted material, and a range of tile types, including roof, flue and hypocaust tiles. Fabric analysis by I Betts at the Museum of London demonstrated that the Reigate tilery had been supplying tiles to major sites in London. (282; see report in SyAC 90, 247-259)

Evaluation by trial trenching of an area to be used as a borrow pit for the Blackwater Valley Route, by Graham Hayman of SCAU for SCC. Occasional features of earlier prehistoric and Roman date were noted, but the principal archaeological interest within the site was evidence for Iron Age settlement. Formal excavation of five areas followed. Two of the excavated areas revealed some features of Iron Age date, but three areas contained the major parts of four substantial Iron Age settlements.

Evaluation and subsequent formal excavation in advance of the Runfold diversion, part of the Blackwater Valley Route, by Graham Hayman of SCAU for SCC, recorded a range of features including ditches, postholes, pits and a small four-post structure. Provisional examination of the pottery suggests that features of Neolithic, Bronze Age, Iron Age, Roman and medieval date were present. A few sherds of Saxon pottery were also discovered. (273)

Observation by G R Pattison and P M G Jones for SCAU of trench cutting for cable TV revealed part of an Anglo-Saxon inhumation with possible grave goods including an iron spearhead and fragments of a pot with rosette stamps. Other finds from the general area included one probably IA sherd, various fragments of RB pottery, mostly 4th century, and some further fragments of Anglo-Saxon pottery.

Evaluation of the disused school site by Tony Champion of SCAU, for SCC’s Resources Dept, found a narrow gully and small pit of unknown date, thought likely to be of some antiquity, and one abraded sherd of Roman date.
